Definitions

  • a wireless transmission device is coupled to the control device such that data of the heart sound patterns database can be received from a remote server or a remote device through the wireless transmission device.
  • An analog-to-digital converter is coupled to the control device such that the heart sound pattern can be converted into a digital heart sound signal.
  • the noise pattern recognizer 104 is coupled to the noise filter 108 and the sound receiver 110 .
  • the noise filter 108 is coupled to the speaker 116 .
  • the function of the noise filter 108 is employed to offset the noise signal generated by the noise source against the corresponding noise pattern (waveform pattern) signal to reduce the noise decibel value (dB value) generated by the noise source.
  • an ambient noise is detected before playing music by an audio device in outdoor, in which noise is reduced during playing and the noise model is refreshed in the playing interval of the music.
  • it is also applicable to play the on-ship audio device. Although this will not completely reduce noise, it will effectively improve the signal-to-noise ratio. In other words, the above-mentioned is applicable to the application of noise reduction in open space.
  • the received noise signal (X) is identified by the noise pattern recognizer 104 , and the preset noise pattern (AL) corresponding to the received noise signal (X) is selected from the noise pattern database 106 by the control device 102 .
  • the message of the corresponding noise pattern (AL) is transmitted to the noise filter 108 by the control device 102 .
  • the smart noise reduction device 300 of the invention is used to filter out the noise such as the friction sound of clothes by the heart sound filter, which can make the device stick near the heart, reduce or eliminate the noise generated by clothes, and achieve the effect of correctly reading the heartbeat sound wave.
  • the smart noise reduction device 300 includes a control device 302 , a heart sound pattern recognizer 304 , a heart sound pattern (HSP) database 306 , a heart sound filter 308 , a sound receiver 310 , a wireless transmission device 312 , a storage device 314 , an A/D converter 316 and a warning device 318 .
  • HSP heart sound pattern
  • the control device 302 is coupled with the HSP recognizer 304 , the HSP database 306 , the heart sound filter 308 , the sound receiver 310 , the wireless transmission device 312 , the storage device 314 , the A/D converter 316 and the warning device 318 to process or control the operations of these elements.
  • the control device 302 is a processor.
  • the heart sound filter 308 is coupled to the HSP recognizer 304 and the A/D converter 316 .
  • the HSP recognizer 304 is coupled to the sound receiver 310 .
